ESP32-CAM I2Cpin

[climbw14769]

hello everyone,this is my first time to ask a question,i am sorry for my bad English
I am creating a project using ESP32-Cam and I2C sensor module(GY-91/MAX30100 etc.)
but all I2C pin is used for other module
I check the esp32 based library
https://github.com/espressif/arduino-es ... -hal-i2c.h
https://github.com/espressif/arduino-es ... -hal-i2c.c

I find a function for change the i2c IO pin,but i can't do it,any one can help me or give me some example code?

Thank you everyone

You can find many examples showing how to use custom selected pind for I2C.

On esp32 cam it will depend on if using sd card or not , but look here for more information:
